clk: sunxi-ng: sun8i-r: Fix divider on APB0 clock

According to the BSP source code, the APB0 clock on the H3 and H5 has a
normal M divider, not a power-of-two divider. This matches the hardware
in the A83T (as described in both the BSP source code and the manual).
Since the A83T and H3/A64 clocks are actually the same, we can merge the
definitions.
